ELECTRIC LOCOMOTIVE.

SPECIFICATION forming part of Letters Patent No. 567,662, datedSeptember 1 5, 1896.

l Application filed September 8, 1895. Serial No. 561,314. `(No model.)

invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to an improvement in electric locomotives; and itconsists in certain novel features of construction whereby to affordsimple and eflicient yielding connections between the motor-casing andaxle.

In the accompanying drawings, Figure 1 is a view illustrating anembodiment of my improvements. Fig. 2 is a sectional view.

A represents an axle having wheels B secured thereto. A frame O ismounted on the axle, so that its free end can swing ver-l tically, andcomprises a sleeve a, made in two parts 1 2, bolted together, andparallel arms b Z). The arms l) o are made at or near their free endswith bearings for the accommodation of hollow trunnions 3, projectingfrom the motor-casing D, said motor-casing also having a suitableflexible connection with the truck-frame of the car. At the side next tothe sleeve a, on the axle, the motor-cas ing is provided at or near itsends with lugs or ears 4, each having an open slot 5 for theaccommodation of a vertical rod or bolt 0. The lower ends of the rods orbolts 6 are made with angular heads 7, having their seats insimilarly-shaped recesses 8 in the bottoms of pockets 9, made on theupperhalf 1 of the sleeve a. The pockets 9 are not directly over thelongitudinal axis of the sleeve, but are disposed to one side orrearwardly thereof, so that the bearings ofthe rods or bolts 6 will notbe `immediately over the longitudinal axis of the axle, but rearwardlythereof. Springs l0 encircle the rods or bolts G and have their bearingsin the pockets 9 and against the under faces of the lugs or ears 4,respectively. Similarsprings 11 are located on the rods or bolts 6between the upper faces of the lugs or ears 4t and disks or washers 12at the upper ends of said rods or bolts. The disks or washers 12 areretained in place on the rods or bolts by means of nuts 13, and thelatter are preferably provided with suitable nut-locks 14. The armatureof the motor is connected with the axle through the medium of suitablegearing, and

the latter is inclosed by a gear-casing 15.

From the combination and arrangement of parts above described it will beseen; that the motor is mounted in a frame connected with the axle andcapable of a vertical swinging motion,.and that the side of the motornext to the axle is flexibly supported by the sleeve of the swingingframe at points outwardly removed from the longitudinal axis of theaxle. IVhile the'motor is located to one side of the axle, it is notsupported solely at one side thereof, but a portion of its weight isbrought to bear on the sleeve of frame O at the side of the axleopposite the motor.

Having fullydescribed my invention, what 'I claim as new, and desire tosecure by Letters l. In an electric locomotive,the combination with anaxle and a swinging frame mounted on the axle, said frame having armsprojecting laterally from the axle, of a motor-casing mounted betweenthe arms of the swinging frame, lugs projecting from said motor-casing,pockets in the swinging frame at the opposite side of the axle from thearms of said frame, rods or bolts passing through said lugs and seatedin said` pockets, `washers or disks at the upper ends of said rods orbolts, springs bearing against said lugs and washers or disks and othersprings seated in said pockets and bearing against the under faces ofsaid lugs, substantially as set forth.

2. In an electric locomotive,the combination with an axle andavertically-swinging frame `mounted on the axle, of a motor-casingmounted in said vertically-swinging frame, lugs projecting from the sideof the motorcasing next to the axle, said lugs being located inproximity to the ends of said casing, pockets on the part of theswinging frame `which is mounted on the axle, rods or bolts seated insaid pockets and passing through the lugs on the motor-casing, disks onthe upper ends of said rods or bolts, springs seated in the pockets andbearing against the lugs and springs disposed between the lugs anddisks, substantially as set forth.

3. In an electric locomoti ve,the combination ICO With an axle and aswinging frame mounted on the axle, of `'a motor-easing mounted in theswinging frame, pockets formed on that part of Jthe swinging frame whichis mounted on the axle, said pockets having recesses in their bottoms,lugs projecting from the motoroasing, rods or bolts passing through saidlugs and having heads seated inthe recesses in the pockets, springs onsaid rods seated in said pockets and bearing against the lugs, and othersprings on said rods or bolts bearing at one end against the lugs on themotoroasing, and disks on said rods or bolts against which the upperends of said last-mentioned springs bear, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing Witnesses.
